Description

Technical Field

[0001] The utility model belongs to the technical field of COB light sources, and in particular relates to a multifunctional two-line light-changing COB light source. Background Art

[0002] The traditional color temperature adjustable COB light source is a COB light source with adjustable color temperature, which is composed of two groups of LED chips with different color temperatures in the form of common anode or common cathode, and three points connected to a constant current source. The common color temperature adjustable COB light sources on the market are all three-wire inputs. The principle is to achieve the target color temperature by applying different voltage values ​​to the two color temperature chips. In the traditional variable light source (taking the common positive pole as an example), when a positive voltage is applied between the + pole and -w, the K1 color temperature chip lights up (white light); when a positive voltage is applied between the + pole and -y, the K2 color temperature chip lights up (warm light). When the voltage is applied between the + pole and -y and -w at the same time, the K1 color temperature chip and the K2 color temperature chip light up at the same time (neutral light). When the voltage value between the + pole and -y and -w changes, the brightness of the two groups of chips changes accordingly, and the overall color temperature also changes, achieving the purpose of adjusting the color temperature. The traditional color temperature adjustable COB light source has a single function. Utility Model Content

When a forward voltage is applied between the w pole (white light) and the y pole (warm light) (w is +, y is 0), the K1 color temperature chip lights up as white light. When a reverse voltage is applied between the w pole and the y pole (w is 0, y is +), the K2 color temperature chip lights up as warm light. When an AC voltage is applied between w and y, the K1 color temperature chip and the K2 color temperature chip light up alternately.

[0024] The light source of the utility model can be directly connected with a traditional monochromatic constant current source, and two color temperatures of white light and warm light can be obtained by changing the polarity of the connection; and neutral light can be obtained by connecting a DC-AC conversion module.

[0025] Embodiment 2, when the light source of the utility model is used as a load of a constant voltage source;

[0026] Connecting the CRD components in series to the constant voltage source provides constant voltage and constant current working conditions for the light source of the utility model;

[0027] When a forward voltage is applied between the w pole and the y pole, the K1 color temperature chip is turned on (white light) and lights up; when a reverse voltage is applied between the w pole and the y pole, the K2 color temperature chip is turned on (warm light) and lights up; when a stabilized high-frequency AC voltage is applied between the w pole and the y pole, the K1 and K2 color temperature chips are turned on and lit up at the same time (neutral light).

The traditional light source power of 3w-12w needs to be divided into multiple chip light sources with corresponding constant current source drivers. The utility model light source only needs one 12w light source chip to get any power of 3w-12w. Similarly, 12w-24w also only needs one 24w light source chip.
